Watertight rope light

Abstract

A watertight rope light of the present invention includes two parallel wires, a plurality of light emitting diodes and a transparent enclosing layer. The light emitting diodes are substantially parallel to the wires. Each light emitting diode has a semiconductor die, a lens, an anode leg and a cathode leg. The lens has a distal end, which is formed with an awl-shaped concave surface, and the semiconductor die is adapted to emit light toward the concave surface. As such, the light emitted from the semiconductor die can be reflected radially outward to illuminate the surrounding uniformly.

1. A watertight rope light, having at least two elongated rope light elements, each of which comprising:
 two parallel wires; 
 a plurality of light emitting diodes, spaced disposed along the wires, an orientation of the light emitting diodes being substantially parallel to the wires, each of the light emitting diodes having a semiconductor die, a lens, an anode leg and a cathode leg, the anode leg connecting the semiconductor die with one of the wires, the cathode leg connecting the semiconductor die with the other one of the wires, the lens enclosing the semiconductor die, the lens having a distal end away from the semiconductor die, the distal end of the lens being formed with an awl-shaped concave surface, the semiconductor die being adapted to emit light toward the concave surface; 
 a transparent first enclosing layer, solidly enclosing the wires and the light emitting diodes. 
 
     
     
       2. The rope light of  claim 1 , wherein a plurality of adapters are disposed between each leg and its corresponding wire respectively, each adapter has a wire groove and a leg groove, the wire groove has two open ends, the leg groove has an open end and a connecting end communicating with the wire groove, the wire groove is adapted to receive a part of one of the wires, the leg groove is adapted to receive a part of one of the legs so as to electrically connect the leg with the wire. 
     
     
       3. The rope light of  claim 1 , wherein a plurality of metal plates are disposed between each leg and its corresponding wire respectively, each metal plate is adapted to sandwich one of the legs and its corresponding wire so as to electronically connect the leg with the wire. 
     
     
       4. The rope light of  claim 1 , wherein the elongated rope light elements are parallelly arranged, a transparent second enclosing layer encloses the elongated rope light elements together. 
     
     
       5. The rope light of  claim 1 , wherein an axis of each awl-shaped concave surface is parallel to that of its corresponding elongated rope light element. 
     
     
       6. The rope light of  claim 3 , wherein each metal plate has an arrow-shaped end and a V-shaped notch end. 
     
     
       7. A watertight rope light, comprising:
 two parallel wires; 
 a plurality of light emitting diodes, spaced disposed along the wires, an orientation of the light emitting diodes being substantially parallel to the wires, each of the light emitting diodes having a semiconductor die, a lens, an anode leg and a cathode leg, the anode leg connecting the semiconductor die with one of the wires, the cathode leg connecting the semiconductor die with the other one of the wires, the lens enclosing the semiconductor die, the lens having a distal end away from the semiconductor die, the distal end of the lens being formed with an awl-shaped concave surface, the semiconductor die being adapted to emit light toward the concave surface; 
 a transparent enclosing layer, solidly enclosing the wires and the light emitting diodes.
